The Research And Application Of The Remote Electric Energy Collection System

The construction of power amount acquisition system is one of the important measures for the power corporations to achieve management and decision-making modernization, as well as to consummate the information management. The construction of power amount acquisition is an automation system which contains main station,acquisition terminal and watt-hour meter.The general structure of the remote power amount acquisition system and all the parts in it are introduced in this paper, which is the design and selection of the acquisition terminal, communication network and main station.32 bit ARM kernel microprocessor which has well capability and low loss is used in the hardware of the acquisition terminal, which can improve the reliability of the system. The terminal supports several watt-hour mater communication protocols, which can be used to acquire the data of variety of watt-hour meters of different manufactures, adaptability, compatibility, and powerful.Taking the different external communications environment into account, Modularization is used in the design of remote power amount acquisition system, which not only can reduce costs, improve reliability, but also adapt to the complex environment field. The construction of system is convenient. The system can be set up flexible and convenient, using a variety of communication plug-ins can implement different means of communication. Also the system supports wired, wireless and other means of communication.Client/ Server structure is used in the background master data management system. Foreground development tool is PowerBuild, and the background database is Oracle. The system has several advantages such as splendid man-machine interface,convenient operation,flexible application,multiform statistical result,intuitionist report forms and convenient data store. It also supplies dynamic power amount query in webpage and watt-hour meter record information query of power plant and substation if the user has corporation Internet or MIS. The statistical and analytic data of real time and exact every kind power amount is powerful tool to modernize the power management of the power supply corporations and power demand corporations.The module of the running conditions supervising of watt-hour mater makes the supervisor discover and conclude the fault kind of the remote meter. The actual wiring hexagonal diagram is given, which can effectively reduce the measured intensity of the work of professionals. The basal unconventionality state supervising methods are described briefly in this paper.
